User blog comment:LegionZero/Anyone Good With Twitter??/@comment-26045423-20190227203103

No Legion. He just made it up. I tend to sit in a discord group that have a lot of people that are patrolling every activity on Itsuno's, Matt and Okabe's twitter. We have some info from -Before the Nightmare- that was translated by skilled people. Not official translation tho.

Basically... Sparda managed to beat both Mundus and Argosax.

We dont know how strong Mundus was compared to other demons... But it says that Dante's power was able to surpass Mundus, Argosax wasn't much of a threat. Also during DMC 2 Argosax was number one in power in demonic ranking and Balrog was number two. (The ranking probably never counted Mundus since he was sealed away during that time).

Matier stopped counting how old she was 100 years ago...

And a lot of more stuff. I can send all of it here, if you want. But be beware... it's fan translated. Nothing official.
